FIELD: powder materials for making coats of items during protracted operation at high working temperatures.
SUBSTANCE: proposed powder material contains the following components: from 40 to 65 mass-% of at least one solid epoxy resin which is semi-functional relative to thermal cross-linking by epoxy groups at equivalent mass of epoxide from 380 to 420 g/eq and ICI viscosity of melt at 150C from 2800 to 5000 mPa·s and softening temperature from 95 to 105C (A); from 15 to 35 mass-% of at least one solid linear epoxy resin on base of bisphenol A , AD and/or F whose functionality relative to thermal cross-linking by epoxy groups is equal to 2 maximum; from 15 to 30 mass-% of inorganic filler (b) and from 1 to 10 mass-% of at least one hardener. Powder material is applied on metal bases and are thermally cross-linked or hardened.
EFFECT: enhanced parameters of elasticity, wear resistance, resistance to scratching; enhanced water prooofness and corrosion resistance of coat.
